Piri Reis (; born Muhiddin Piri 1465–1470; died 1553) was an Ottoman Turkish cartographer, admiral, and corsair. He is best known for his 1513 world map and his nautical atlas, the Kitab-ı Bahriye (Book of the Sea). His cartography engaged more directly with the Age of Discovery than other Ottoman works from the period. His maps provide a glimpse into the world during a time of major geopolitical change, when the Americas were explored and the Ottoman Empire came to dominate the Eastern Mediterranean.
Piri Reis began his maritime career sailing with his uncle, the corsair Kemal Reis, with whom he entered Ottoman naval service. He later commanded his own ship in the Ottoman–Venetian wars and, after his uncle's death, began the cartographic work. After blockading the port of Alexandria during the 1517 conquest of Egypt, Piri Reis presented his world map as a gift to Selim I, and he dedicated his atlases to Selim's successor, Suleiman the Magnificent. Decades later, as grand admiral of the Ottoman fleet in the Indian Ocean, Piri Reis led successful campaigns in the Red Sea, but was beheaded following his retreat from the siege of Hormuz.
During his lifetime, Piri Reis's cartography received little appreciation, but many copies of the Kitab-ı Bahriye were produced after his death. The 1929 rediscovery of his first world map, during renovations to the Topkapı Palace in Istanbul, sparked interest in his work largely because it cites a now-lost map by Christopher Columbus. While the rediscovery made his achievements a point of national pride for Turkey, the map became the subject of fringe theories based on the disproven hypothesis that it depicted an ice-free Antarctica. Studies have shown no significant similarities between the map's southern coastline and Antarctica's coast beneath the ice. Nevertheless, this speculation has broadened popular interest in his work.
Early life and piracy
The only surviving primary sources covering Piri Reis's early life are his own cartographic works, in which he identifies himself as Muhiddin Piri, son of Hacı Mehmed.. Piri Reis was likely born between 1465 and 1470 in Gelibolu (Gallipoli), in present-day Turkey. This was a major naval base for the Ottoman Empire, a Muslim power in the Mediterranean spanning from Anatolia in Asia into Eastern Europe. The 16th-century Ottoman historian Ibn Kemal wrote that Gelibolu had a strong maritime tradition where the town's children were "rocked to sleep with the lullaby of the sea and of the ships day and night"a culture that, according to Turkish historian Afet İnan, shaped his upbringing..
His uncle Kemal Reis was a notable corsair, a type of state-sanctioned pirate, often operating along religious lines in the Mediterranean. Serving under Kemal, he earned the rank of reis himself, equivalent to a captain..
Cartography scholar Ibrahim Yilmaz suggests Piri Reis's parents likely died around 1481, after which he began working aboard his uncle's ship.. Years later, Piri Reis described how, shortly after he began sailing with his uncle, a storm nearly destroyed Kemal Reis's galley in a small stony harbor near Mount Athos in present-day Greece. While they were sheltering from rough seas, Eastern Orthodox monks came to the water with ropes and tied the galley down until the storm passed..
Under Sultan Bayezid II's approval, Piri Reis sailed west with Kemal Reis and other Ottoman corsairs to fight the Iberian Catholic Monarchs and aid the Emirate of Granada, the last Muslim-ruled territory in Iberia. As a young man, he helped his uncle bombard the forces besieging Málaga in 1487..
By the end of 1487, Málaga fell to the combined Catholic armies. Barbary corsairs based in northern Africa and led by Kemal Reis continued to threaten European maritime traffic. Corsairs differed from typical privateers because they operated outside a defined time of war. The perpetual Holy War in the Mediterranean gave them an indefinite license. Piri Reis described himself and his uncle as "sea gazis".. He wrote: "We sailed on the Mediterranean and fought the enemies of our religion mercilessly." During the winters, they took shelter in harbors along the Barbary Coast of North Africa, including Béjaïa and Annaba in present-day Algeria. For six years, they sailed north to raid the coasts of Spain and France, as well as the islands lying between Europe and Africa: Corsica, Sardinia, Sicily, and the Balearics..
Drawing from firsthand experiences, Piri Reis recorded life on the Balearic Islands during the final years of Muslim rule in Iberia. Near the piers of Ibiza, he observed ships loading salt and noted that there were more "Turkish and Arab captives in this salt mine" than anywhere else in the islands. He wrote that in the Gulf of Mahón on Menorca, a fig tree marked a natural spring where there was "never any lack of Arab or Turkish" ships, as a large mountain obscured this spring from the nearby castle. He described the rivers of Mallorca and praised its olive oil. Invasive rabbits overran the tiny islet of Cabrera off Mallorca's coast, and the galley's crew "caught three hundred seventy or so" on a hunting trip.. While sheltering in a cove on Mallorca, the Turks were caught unaware by Christian corsairs. A young Muhiddin Piri watched "eleven of [his] comrades" die in the fight..
Granada fell in 1492.. Many Muslims fled Iberia rather than remain as Mudéjars, permitted to practice their religion but denied full participation in Catholic Spanish society. When Spain expelled its Jewish population outright in 1492, Sultan Bayezid II instructed Kemal Reis to aid religious refugees. In response, Piri Reis ferried Muslims and Jews from Spain to North Africa..
Naval career and cartography
Like many Ottoman corsairs of the period, Piri Reis and his uncle were recruited into the Ottoman Navy by Bayezid II. For Kemal Reis and his contemporaries, the boundaries between outright piracy, state-sponsored corsairing, and formal naval service were fluid..
After Kemal Reis was imprisoned for piracy in 1495, the sultan granted him an official position in the navy instead of further punishment.. As recorded in the Kitab-ı Bahriye, Kemal Reis and Piri Reis advised the sultan to take the strategically valuable island of Rhodes. Just off the coast of Anatolia, Rhodes was close enough to threaten the sea lanes between the empire's European capital and its Mediterranean ports. They also advocated seizing the Venetian coastal fortresses on the Peloponnese..
Around the turn of the century, Piri Reis fought in the Ottoman–Venetian wars as a captain under his uncle's command. Like other Ottoman captains, he operated a galley, a shallow oar-driven warship well suited to the Mediterranean coasts.
During the 1499 Battle of Zonchio, Piri Reis piloted one of the 270 Ottoman ships that broke through the 150-ship Venetian fleet to enter the Gulf of Corinth, forcing the Venetian governor to surrender.. After further victories under Kemal Reis at Modon and Navarino, the Ottoman Navy began to consolidate control over the Eastern Mediterranean. Piri Reis returned to the Western Mediterranean, raiding the coasts of Spain and nearby islands in 1501 alongside his uncle.
In a naval battle near Valencia, they captured a Spaniard who said he had sailed with Columbus and likely possessed one of the explorer's charts of the Americas. They also seized exotic New World materials, including parrot feathers and unusual black stones, possibly obsidian, that could cut metal. In 1502, Piri Reis and his uncle returned to Constantinople and resumed hostilities with Venice..
Piri Reis last saw his uncle in 1510.. He was the captain of his own ship, but Kemal Reis remained his mentor, commanding officer, and patron. They returned from Tripoli in North Africa, where the locals had asked Kemal Reis to become their governor and protect them from Spain. On 25 July 1510, Spain seized Tripoli while the Ottomans were still traveling to Constantinople. In the capital, Sultan Bayezid II tasked Kemal Reis with delivering aid to Egypt against Portuguese incursions, though Piri Reis remained in Europe. Kemal Reis drowned at sea; his ship sank in a storm near the island of Samos. News of his death reached Cairo in February 1511, and a Venetian report claimed that Kemal Reis had been sabotaged when İskender Ağaa rival who became admiral of the Ottoman Navy in 1511sent Kemal to sea in "an unsound ship". The Kitab-ı Bahriye contains a eulogy for Kemal Reis:
After his uncle died, Piri Reis returned to Gelibolu to focus on his cartographic work.. There, he completed the world map for which he is best known today. Dated to Muharram 919 AH in the Islamic calendar (March 1513 AD), the manuscript depicts the recently explored shores of the Americas and Africa. When Piri Reis resumed sailing along the North African coast, he did so under the corsair Hayreddin Barbarossa. Around 1515, to establish ties with the new sultan, Selim I, Hayreddin sent a captured ship laden with wood to Constantinople under Piri Reis's commanda delivery the sultan rewarded with two galleys and a robe of honor.
During the 1516–1517 Ottoman conquest of Egypt, Piri Reis commanded the ships blockading Alexandria, and after the empire's victory, he presented his 1513 world map to Sultan Selim I. How Selim used the map is unknown, as it vanished from history until its rediscovery centuries later..
His relationship with the Ottoman state frayed after the conquest of Egypt, when he was among several captains who left the Ottoman Navy.. Contemporary historian Marino Sanuto the Younger wrote that they "rebelled against the sultan" and "were able to land 800 men"including relatives of Kurtoğlu Muslihiddin Reison the island of Chios, where they captured a castle and "400 of the sultan's subjects" in February 1518. When Venetian ambassador Alvise Mocenigo returned from Constantinople, his ship's captain steered into a storm rather than risk capture by Piri Reis. The rebellion continued into May, when he was recorded raiding the island of Euboea and the coast near Athens. It was short-lived: Kurtoğlu was given command of an Ottoman fleet in 1518, and Piri Reis was back in Ottoman service before the conquest of Rhodes.
The reasons for his brief defection remain unknown. By 1522, Piri Reis rejoined the Ottoman Navy and took part in Sultan Suleiman the Magnificent's Siege of Rhodes, for which he had advocated. Controlled by the Knights of St. John, the island provided shelter to Christian pirates..
Suleiman became sultan in 1520, and craftsmen across the empire presented exemplars of their work in hopes of winning favor. By 1521, Piri Reis had offered the first version of the Kitab-ı Bahriye, a nautical atlas that included advice on conquering Rhodes. There is no evidence the gift received any response. A second version, completed after the conquest, only discussed the siege of Rhodes in terms of acquiring drinking water..
When putting down Hain Ahmed Pasha's 1524 rebellion in Egypt, the Ottoman grand vizier and sultan's childhood friend Pargalı Ibrahim Pasha rode aboard the navy's flagship, commanded by Piri Reis. The two pashas were unrelated; the title was the highest the sultan bestowed on Ottoman officials. The longer second version of the Kitab-ı Bahriye resulted from a conversation with the grand vizier, who asked about the maps and charts used aboard the ship. Ibrahim commissioned the expanded atlas, which Piri Reis presented to the sultan by 1526. Ibrahim Pasha was executed in 1536, and no surviving works of Piri Reis's cartography date past this point..
